My hunt for quality headphones and a headphone amp has begun! I'm going to be running the record out from my Rega Brio R to the headphone amp, and my sources are a Rega RP1, a Yamaha CD-S300. and a Chromecast Audio. I don't know if this information is helpful to you, but keep in mind that I am not looking for a portable amp, and my headphones are going to stay right next to my listening chair. My budget is around $600 for both. I've been looking at the Beyerdynamics 880s, but this is my first time venturing into quality headphones. Should I spend more on the headphones than the amplification or about equal? My mind is telling me to spend 300 on a nice amp and 300 on a nice pair of cans, but my body is telling me to slow down. Also, should I go high or low impedance? I had planned on high impedance since I don't intend to use them anywhere other than at home with my amp. I have cheaper headphones for traveling. Any recommendations for headphones or amps? Thanks mates.
